If this has not been posted before....perhaps a moderator could sticky this. The links below offers an invaluable source of parts for a huge range of synths etc. Now you dont have to worry so much about sourcing 'rare' parts.

i'd been digging around for a while for a MIDI to DIN SYNC converter to be able to slave my TR-808 to gear that doesn't have a DIN SYNC out. there are several options out there, but the one i went with i am thrilled by. guy in australia is making them, they're simply an adapter that attaches to a midi cable, plus they don't even need a power supply!
